Definitions

  • This invention relates to bobbin winding machines and more especially to machines which are used for winding a thread of artificial silk upon a bobbin.
  • my invention relates to a novel method of operating bobbin winding machines and of winding thread upon a bobbin.
  • My invention may be used with advantage for winding cylindrical as well as conical bobbins which, moreover, may be bevelled at one or both of their ends.
  • My invention furthermore provides a novel machine for making cross-wound bobbins as well as a novel method of winding bobbins of this kind.
  • a primary object of my invention as far as it relates to the method of winding bobbins, especially bobbins of artificial silk, consists in providing possibilities to wind the bobbins at even speed of the thread, independently of their temporary thickness which increases during winding, and to dispense at the same time with any roller which had ordinarily been used for driving the bobbin.
  • a further object of my invention consists in a novel construction of a cross-winding machine for making cylindrical bobbins.
  • a still further object of my invention consists in a novel construction of a cross-winding machine which may be used for winding bobbins which are bevelled on one or both of their ends.
  • a still further object of my invention consists in a novel construction of a cross-winding machine for winding conical.
  • bobbins in which, in addition to the conical shape, one or both ends of the bobbins may be bevelled.
  • I make use of a change speed drive permitting to maintain automatically the speed of the thread at a constant value, while the thickness of the bobbin increases during the process of winding.
  • the thread-guide of the present 40 machine is connected with a feeding device permitting to vary and adjust automatically the path of motion of said thread-guide.
  • This feeding device in conjunction with a swingable bail will permit adjustment of the driving mechanism of the thread-guide with respect to the cam disk in radial direction to the latters axis of rotation and impart a swinging motion to said threadguide relatively to the cam disk.
  • This swinging motion now is transmitted, for instance, to a friction drive in such a manner that the driving disk of said friction drive is displaced with respect to the driven disk in radial direction towards the periphery of the latter, this eifecting a gradual reduction of the speed of rotation of the spindle which serves for rotating the bobbin, thus dispensing with the roller for the immediate drive of said bobbin.
  • My new winding machine may also be used in connection with conical bobbins, the cam disk which rotates obliquely around its axle being in this case controlled by means of a further gearing comprising elliptical gear wheels, the retardation and acceleration produced thereby being positively transmitted to the guide-thread with the result that, in spite of the conical form of the bobbins, the speed at which the thread is wound upon the latter is kept continuously uniform and independent of the thickness of the bobbin.
  • the bobbin winding machine may be constructed according to my invention either for winding one bobbin at a time or also for winding a plurality of bobbins simultaneously.
  • Fig. 1 being a longitudinal section, with several parts in view, of a machine serving for the purpose of uniform cross-winding of cylindrical bobbins which may be bevelled either at one or both of their ends

  • the cam or eccentric may be made exchangeable, if desired.
  • a bail 42 which is bent off at its free end is fixed to the connecting member 20, the wire 26 being carried over said free end of said bail.
  • the bent off free end of the bail 42 as well as the eccentric 40 are of such conformation that the rotation of the hollow shaft 21 and therewith the adjustment of the friction wheel 3 will be adjustably dependent upon the speed of rotation of the shaft 16.
  • Cress-wound bobbins may be made at a constant speed of the thread during increasing diameter of the bobbin in the following manner.
  • the friction disk 3 which is mounted displaceably upon the motor-driven shaft 1 is adjusted at the start of the process of winding to be positioned at the center of the driven disk 8.
  • the spindles 15 and 15 upon which the bobbins are wound will thus be given the greatest speed of rotation so that, for instance, 250 meters of thread per m nute may be wound upon the empty bobbincylinder.
  • the cam disk 17, when rotating, will reciprocate the member 18 which forms part of the thread-guide.
  • the disk 27 on the shaft 16 now actuates intermittently the feed-wheel 31 by means of the lever 30. Rotation of the feedwheel is transmitted by means of the worm 34 to the worm-wheel 35, and further to the wormwheel 38 by way of the worm 37.
  • the wormwheel 38 mounted upon the axially displaceable shaft 39 drives the eccentric 40, thus adjusting by means of the tension wire the bail 42 and therewith also the rod mechanism 18, 19, 21 against the action of the spring 25.
  • This motion now serves to adjust the guide-member 18 with respect to the cam disk 17. More particularly, this adjustment is effected towards the center of said disk as shown in dotted line in Fig. 3.
  • the degree of intermittent feeding is varied on the feeding device by radially adjusting the crank-pin 29 on the disk 27, as may be seen from Fig. 4.

  • gear-wheel 42 which is in mesh with a gearwheel 43.
  • gear-wheel 44 is mounted upon the shaft of the gear-wheel 43, said gearwheel 44 meshing with the gear-wheel 45.
